Eylo


Eylo or Gilo is the first attested count of Álava. He is known from the chronicle of Sampiro, written in the first third of the eleventh century, which presents him as a rebellious subject of the Kingdom of Asturias, strongly suggesting that he was not appointed count by the king but was instead the leader of a rebellion. After King Alfonso III marched an army into Álava, the people submitted and Eylo was taken into captivity and brought back to Alfonso's capital of Oviedo.
Sampiro presents the story of Eylo immediately after his account of the usurpation of Fruela, which took place in 866–67 and which forced Alfonso III to take refuge in Álava. In these years, there were also major attacks on Álava from the Emirate of Córdoba to the south. The Emir Muhammad I launched a major raid ending in a pitched battle in 866 and his son al-Hakam invaded the region again the next year. It is unlikely, therefore, that Eylo's rebellion took place before 868. The Chronicle of Albelda, written around 881 in neighbouring Navarre, refers to "much time having passed" in 873 since the rebellion, although it does not mention Eylo by name.
Sampiro's chronicle is preserved in two twelfth-century copies: that made by Pelagius of Oviedo for his Chronicon regum Legionensium and that made for the Historia silense. They differ in the spelling of the count's name. The copy of Pelagius uses Eylo and the Silense uses Gilo. It is possible that the obscure Eylo is the same person as the next known count of Álava, Vela Jiménez, active in 882–83. The name Vela appears in Latin documents in various declensions as Vigila, Vigilonis and Vigilonem. If the spelling Gilonem is the more authentic for the earlier count, it may represent a shortened form of Vigilonem. If they are the same person, then Alfonso III must at some point have released his prisoner and put him back in power.
